in the meat industry, pulp already in other meat products is sprayed with preservation or salting) solution of meat u o k t e? n s a j löm.i se κ si and mausi a - for me. In order to achieve proper preservation and taste, it is very important that the liquid is sprayed in a carefully controlled amount, 2 64268 which is evenly distributed in the product.

The generally accepted method for preserving pulps and other meat products today is to inject a solution of preserved or preserved solution through a series of needles, after which the product is smoked to assist. For stallions, it is very important that a carefully controlled amount of solution is injected into the product. The most preferred amount depends on several factors.

U 01 - p a p e n t i o n 3,803,556 disclosed to the prior art, the apparatus comprised a machine for injecting liquid into meat products with the aim of detecting the thickness of the products and injecting a corresponding amount of liquid for injection into them. In the injection according to said patent, the amount of the injection is determined by the length of the control valve. i is open, and the time the control valve is open is determined by the thickness of the meat product. In the applicant's previous device, the measuring rod moves downwards and ends on the surface of the product, and the average height of the measuring rod determines the time during which the flow is open. The applicant's prior device used an eccentric device 11a to control the desired open time of the valve based on the thickness of the meat product and also other factors such as the leakage characteristics of the thick product compared to the thin product. As shown, the amount of spraying on the applicant's previous machine depends on the time the flow valve ij i is open. This time factor does not change in exactly proportion to the thickness of the product due to the action of the palm that moves the fluid nozzle unit and needles up and down. Ts. puhjakohdassa the palm of its stroke the needles takes a half-inch-long circulation time considerably longer than the stroke length corresponding to the middle of the circulation. For this reason, the timing of the valve becomes complicated, and the control very difficult to adjust.

It is impractical to move the needles at a constant speed into the meat product.

It is therefore common in the art to use an eccentric or crank, in which case the needles move eccentrically into and out of the meat product. This means that the speed of the needles varies through the turn and retraction stroke. The speed of the needles starts at zero ^ at the top of the night stroke, moves to the maximum speed in the middle of the push stroke and decelerates to zero speed when the maximum push-in ti z, V * * ό foo 4 £ 6 h is reached and the return stroke starts P a J ui: idku 'i ncpeusköy rr va ·· c ..

The injection machine of the invention is generally indicated by reference numeral 10 and is substantially similar to the injection machine 10 disclosed in U.S. Patent 3,687,058 and substantially similar to the injection machine 10 disclosed in U.S. Patent 3,863,556, for which reason it is not described in detail but only refers to the descriptions of said patents. which supplement this description of the invention.

The machine 10 generally has a table 11 in which a conveyor 12 is arranged for conveying the meat product in Fig. 1 from right to left.

Reference numeral 14 denotes a power unit projecting from a transmission shaft 16 driving a fluid pump 18 and extending from a chain 20 to a sprocket 24 mounted on a shaft 26, said shaft being mounted on a rotating machine 10. The opposite ends of the shaft 26 are provided with eccentrics 28 and 30. Reciprocating arms 32 and 74 are connected to the centers 28 and 30, and their upper ends 64268 are pivotally connected to the fluid nozzle support arms 36 and 38, one end of which is pivotally connected to the machine, as shown in the drawings. The fluid nozzle device 40 is mounted on the free ends of the arms 36 and 38 as shown in Figure 12, and this will be explained in more detail below. The rods 42 and 44 are connected to the eccentrics 28 and 30 in a conventional manner and are further operatively connected to the conveyor device 12 for driving it.

The eccentric disc 46 is attached to the shaft 26, as shown in Figs. The shaft 48 is mounted rotatably on the machine 10 and its crank 50 is attached to one end thereof and the crank 52 to its central stages. The eccentric roller 54 is attached to the crank 52 and engages the guide surface of the eccentric disc 46. The arm 51 is pivotally connected to and extends downwardly from one end of the palm 52 and secured to an air or spring type shock absorber, generally indicated by reference numeral 57, which resiliently forces the palm 52 downwardly so that the roller 54 remains in contact with the eccentric guide surface 46.

The lower end of the rod 58 is pivotally connected to the crank 50 and extends upwardly therefrom as shown in the drawings. According to Figures 1 and 11, the crank 50 is provided with an elongate slot 60 which adjustably receives the rod 58, allowing the displacement or movement of the rod 58 to change. The upper end of the rod 58 is generally connected to the lever device shown by reference numeral 62. The angle lever device 62 includes a triangular plate 64 to which the upper end of the rod 58 is pivotally connected at 66.

The plate 64 is rigidly connected to the shaft 68 at 70 so that the pivoting movement of the plate 64 causes the shaft 68 to rotate. The shaft 68 is rotatably mounted at its opposite ends on the machine, as shown in Figure 12. The lug or bracket 72 is rigidly attached to the shaft 68 and protrudes therefrom and is pivotally connected to a rod 74 which protrudes substantially horizontally therefrom. The rod 76 is pivotally connected at one end to the plate 64 and extends therefrom substantially horizontally parallel to the rod 74. Shaft 78 is secured and extends between rods 74 and 76 and pump rods 80, 82, 84, 86, 88 and 90 extending therefrom are secured thereto. The pump rods 80, 82, 84, 86, 88 and 90 extend from the compressed air pumps 6 64268 92, 94, 96, 98, 100 and 102, respectively. Since all compressed air pumps are identical, only one pump and its associated parts are described in detail. Figures 6, 7 and 8 show a typical compressed air pump device. According to the drawings, a compressed air pump is mounted on a pump body, generally indicated by reference numeral 104. The compressed air pump 92 includes a piston 106 coupled to move with a rod or arm 80. As shown in Figure 6, the inner end of the piston 106 is provided with a seal 108 which adheres tightly to the inner wall surfaces of the pump 92. For shear reasons, the interior of the pump 92 is shown at 110. The pump 92 includes an inner wall portion 112 having an opening 114 formed therein. The opening 114 communicates with a downwardly extending bore 116 in an opening 118 formed in the valve shell 120. The valve 122 is movably mounted in the housing or housing 120 and it is associated with a spring 124 which pushes the valve 122 from the positions shown in Figure 6 to the position of Figure 7. The valve 122 is provided with an annular spool portion 126 formed between the ends of the valve. The valve 122 is provided with an outer end 128. The inner end of the valve shell 120 communicates with a fluid reservoir or chamber 130, which in turn communicates with a source of pressurized injection fluid. The valve housing 120 has an exhaust port 132 which communicates with a passage 134 projecting therefrom.

By adjusting the displacement of the rod 58 while it is mounted in the slot 60 of the palm 50, the amount of fluid supplied by each pump can be precisely adjusted. This distinguishes the present invention from known devices such as those disclosed in, for example, U.S. Patent 3,381,603, issued May 7, 1968, in which the device shown does not have any means for controlling the amount of liquid supplied by the pumps to the meat product.

The liquid nozzle unit 40 has six individual liquid nozzles, designated 136, 138, 140, 142, 144 and 146. Since all liquid nozzles and their support structure are similar, only one liquid nozzle 146 and related parts will be described in detail below. Each liquid nozzle moves up and down as a unit due to the fact that they are attached to the arms 36 and 38. Each liquid nozzle is provided with a plurality of injection needles 150 extending from that nozzle and adapted to protrude into the meat.

II

7 64268 to a product or the like generally indicated at 152. According to Figure 4, each injection needle 150 is slidably fitted with bores communicating with the channel 134. In each of these testers, a release plate 154 is slidably fitted thereto, as in the figures. 3 and 4 are brochures. The detachable plate 154 is provided with a plurality of openings formed therein through which the injection needles 150 protrude. The release plate 154 includes an upwardly projecting portion 156 having a rod 158 attached to its upper end and projecting inwardly into the cylinder 160. As shown in Figure 5, a piston 162 is disposed at the upper end of the rod 158 to engage the inner wall surface of the cylinder 160. Cylinder 160 is secured to support 164 by bolts] 66. The support 164 is rigidly attached to the fluid nozzle to move with it. The valve actuator arm 168 is pivoted at its lower end to the release plate 154 at 170 and extends upwardly and laterally therefrom, as shown in Figure 4. The bobbin 172 is rotatably mounted on the support 164 and engages the surface 174 of the actuator 168. As shown in Figure 4, the surface 176 of the actuator 163 engages one valve associated with the pr * i nep pump i. The roller 172 is adapted to settle in the recess 172A in the actuator 168 (see Figure 1), so that no liquid can flow through the valve 1.22.

When it is desired to inject a meat product or the like, the meat product 152 in question is placed and the engine 14 is started. Starting the motor 14 starts the pump 13 so that the injection fluid enters the chamber 133. Starting the motor 14 also causes the shaft 26 to rotate, which is why the fluid nozzle unit 40 moves back and forth up and down. Rotation of the shaft 26 also causes the rods 42 in 44 to reciprocate so that the moving device moves the meat product from one end to the other back and forth below the liquid nozzle unit. Assuming the liquid extractor unit 40 is in flight, the position of the eccentric disk 46 relative to the rotor 52 is such that the rod 58 is in its uppermost position, causing the rods 80, 82, 84, 86, 88 and 90 to be withdrawn from the cylinders of the pressure pumps. Γ in eno straw the effluents I y the liquid moves from compartment 130 ven 11 i .i 1 i through a bore 116 upwardly through a bore 116, through an opening 114 into a compartment 110. Such fluid filling into the compartment 110 is possible because the spring 124 forces the valve 122 to the right and because the fluid nozzle unit 40 is in its uppermost position, the actuator L60 is not in sufficient contact with the outer end of the valve. .

As the nozzle unit 40 moves downward, each release plate moves downward with its own fluid nozzle due to the resistance provided by the piston 162 in the cylinder 160. When the release plate portion 154 adheres to the top surface of the meat product 152, the release plate portion 154 stops its downward movement, but the liquid nozzle continues its downward movement or overhangs. As the fluid nozzles 11 move past the release plate, the fluid nozzle roller sn a causes the actuator 168 to rotate counterclockwise as shown in Figure 4, which in turn moves the valve 122 inwardly into its housing 120 so that fluid can pass through part 114 of the opening 114, bore 116, orifice 118. , through the opening 132 into the channel 134 due to the position of the valve 122, as shown in Fig. 6. If nothing else were done at this stage, no liquid would transfer to the liquid nozzle, because there is no pressure in the section 110 until the pressure puff moves to the right Le in Fig. 6. The displacement of the pressure pump is controlled as described above in order to coordinate the displacement of the pressure pumps or their operation. tee rt. In this case, when the eccentric nozzle 46 moves the rods of the pressure pumps inwards, the pressure pump moves a predetermined amount of injection liquid n * stes jj11imaen, and the amount of liquid fed to the liquid nozzle depends on the amount of liquid that has passed the valve 1.22. It is clear that if the release plate detects a very thick meat product, the roller 172 will turn the drive 168 much earlier during the downward movement of the fluid nozzle, causing more injection fluid to enter the fluid nozzle. 're ·: .la 172 normally rests in the cavity 172A until the needles are inserted into the Meat Product, so the fluid flow is cut off when the moon needles do not push into the meat product.

by arranging several release plates and pressure or transfer pumps, it is possible to detect the thickness of the meat product much more accurately, as shown in Fig. 3.

il 9 64268 For the purposes set forth herein, the downward stroke of the needles is described as the push stroke and the upward stroke as the return stroke. In fact, the needles are inserted into the meat product only during the lower phase of both push and return strokes. The speed of the needles peaks at the middle of each stroke and returns to zero speed in the blink of an eye at the end of each stroke.

The eccentric disc allows fluid to be fed through the needles during both push and return strokes. If a crank were used instead of an eccentric disc, the fluid would only be able to flow during the second stroke, but not during the second. As discussed above, means are provided to provide fluid flow through the needles only when the needles are in the meat product. An important phenomenon, however, is that the eccentric disc 46 and the pump would be able to supply fluid through the needles at a rate proportional to the speed of the needles, even if the fluid could flow throughout the push and return strokes and not only when the needles are in the meat product itself.

Thus, it can be seen that a machine is provided in which the injection liquid is fed to the meat product, whereby the detachment or measuring rod unit detects the thickness of the product, and such detection is used to control the pump output volume rather than the time element. By using a simple pressure or transfer pump whose stroke is timed to the stroke of the injector, it is possible to control the displacement towards the injection. Such a method provides a much better and simpler way to precisely control the desired spray rate. Thus, it can be seen that the machine achieves all the stated purposes.
